How to keep Analysis for Office workbooks changing the datasource query

Hi all,

     We have many customers using complex Analysis for Office workbooks created by themselves, however they were using 3.x queries and now we need to replace the queries with 7.x queries with a different technical name.

    We tried by changing the datasource in "components", here we change the 3.x query for the new 7.x query. The problem is that the workbook layout is changed to the initial layout of the query, the workbook layouit saved by the user changes.

   Do you know a way to chenge the query behind keeping the layout of the workbook?

Thanks in advance
